Debugging stepping in to built-in units like System or CRT? lazarus / 12-Debugger ---------------------------------------------------------------------- dfatl · 2023-02-14 01:17 Hello, In this Windows console application I was testing the debugger and using F7, but it didn't trace in to things like "GotoXY(1,1)" it still stepped over it.   Virtual Pascal which I am currently using traces into the various units.  Is there an option to enable that in Lazarus?  Also startup code / auto initialization code. TIA!! ---------------------------------------------------------------------- marcov · 2023-02-14 08:24 It requires an RTL compiled with debug info, and then it will trace into anything, even implicit string copying. (which why it isn't default). You can probably build a complete system (FPC+Lazarus) with such debugging use FPCDELUXE.
